Prediction of nuclear products both for metaldeuterium systems and metal protium systems is made on the basic physics of cold fusion by the TSC (tetrahedral symmetric condensate) theory. This paper focuses on final state nuclear reactions of intermediate compound states as 8Be* of 4D/TSC fusion and 4Li* of 4H/TSC WS fusion. Prediction of final products is made by the nucleon-halo model of the h...
Karyogamy, or nuclear fusion, is essential for sexual reproduction. In angiosperms, karyogamy occurs three times: twice during double fertilization of the egg cell and the central cell and once during female gametophyte development when the two polar nuclei fuse to form the diploid central cell nucleus. The molecular mechanisms controlling karyogamy are poorly understood. We have identified nin...
New mutations were isolated that affect nuclear fusion during conjugation in the yeast Saccharomyces cerevisiae. These mutations, called kem (Kar enhancing Mutation), enhance the nuclear fusion defect of the karl-l mutation. In crosses of karl-l strains, 10 15% of zygotes undergo nuclear fusion forming stable diploids whereas 85 90% of zygotes fail to have nuclei fused. The nuclear fusion defec...
Fusion nuclear technology (FNT) research in the United States encompasses many activities and requires expertise and capabilities in many different disciplines. The US Enabling Technology program is divided into several task areas, with aspects of magnet fusion energy (MFE) fusion nuclear technology being addressed mainly in the Plasma Chamber, Neutronics, Safety, Materials, Tritium and Plasma ...
Histone-beta-galactosidase protein fusions were used to identify the domain of yeast histone 2B, which targets this protein to the nucleus. Amino acids 28 to 33 in H2B were required for nuclear localization of such fusion proteins and thus constitute a nuclear localization sequence. The amino acid sequence in this region (Gly-29 Lys Lys Arg Ser Lys Ala) is similar to the nuclear location signal...
A convenient assay for monitoring nuclear localization signal-mediated nuclear import of green fluorescent protein (GFP)-variant fusion proteins has been developed. This modified assay relies upon indirect immunofluorescence microscopy for visualization of transported substrates. The use of GFP-variant fusion proteins allows for the rapid assessment of optimal digitonin concentration and permit...
The possibility of using cold fusion for nuclear waste products transmutation is investigated in this paper. In generally a method is based on saturation of the titanium by a mixture of deuterium and air. Possible nuclear fusion reactions are discussed. Their “burning out” sections, effective half-life periods and intensity of neutron beams are evaluated. The applicability of the method for a t...
Membrane fusion plays a central role in many cell processes from vesicular transport to nuclear envelope reconstitution at mitosis but the mechanisms that underlie fusion of natural membranes are not well understood. Studies with synthetic membranes and theoretical considerations indicate that accumulation of lipids characterised by negative curvature such as diacylglycerol (DAG) facilitate fus...
Cryptochrome 2 is a flavin-type blue light receptor mediating floral induction in response to photoperiod and a blue light-induced hypocotyl growth inhibition. cry2 is required for the elevated expression of the flowering-time gene CO in response to long-day photoperiods, but the molecular mechanism underlying the function of cry2 is not clear. The carboxyl domain of cry2 bears a basic bipartit...
